.SH NAME
std::experimental::erase_if(std::basic_string) \- std::experimental::erase_if(std::basic_string)

.SH Synopsis
   Defined in header <experimental/string>
   template< class CharT, class Traits, class Alloc,
   class Pred >                                            (library fundamentals TS v2)
   void erase_if( std::basic_string<CharT, Traits,
   Alloc>& c, Pred pred );

   Erases all elements that satisfy the predicate pred from the container. Equivalent
   to c.erase(std::remove_if(c.begin(), c.end(), pred), c.end());.

.SH Parameters

   c    - container from which to erase
   pred - predicate that determines which elements should be erased

.SH Complexity

   Linear.

.SH Example


// Run this code

 #include <experimental/string>
 #include <iomanip>
 #include <iostream>

 int main()
 {
     std::string data{"1337!p_C00L_<a-_HACKER_!@s_(!s#@_w^o%r*d#42"};
     std::cout << "Original string: " << std::quoted(data) << '\\n';
     auto crack = [](auto O) { return '`' ^ ('`' & O); };
     std::experimental::erase_if(data, crack);
     std::cout << "After erase_if:  " << std::quoted(data) << '\\n';
 }

.SH Output:

 Original string: "1337!p_C00L_<a-_HACKER_!@s_{!s#@_w^o%r*d#42"
 After erase_if:  "password"
